Исследования пленок проведены с использованием рентгеноструктурного анализа, сканирующей электронной микроскопии, рентгеноспектрального анализа с энергетической дисперсией, низкотемпературной фотолюминесценции, оптического пропускания и отражения. В необлученных и облученных протонами тонких пленках Cu(In,Ga)Se2 обнаружено стимулированное излучение при низких температурах (~20 К) при возбуждении импульсами лазерного излучения наносекундной длительности с пороговой плотностью мощности ~20 кВт/см2. Показано, что появление и параметры стимулированного излучения сильно зависят от концентрации ионно-индуцированных дефектов в тонких пленках Cu(In,Ga)Se2. </p></abstract><trans-abstract xml:lang="en"><p>Stimulated emission, optical properties, and structural characteristics of non-irradiated and proton-irradiated Cu(In,Ga)Se2 thin films deposited on soda lime glass substrates using co-evaporation of elements in a multistage process were investigated. X-ray diffraction analysis, scanning electron microscopy, X-ray spectral analysis with energy dispersion, low-temperature photoluminescence, optical transmittance and reflectance were used to study the films. Stimulated emission at low temperatures of ~20 K was found in non-irradiated and proton-irradiated Cu(In,Ga)Se2 thin films upon excitation by laser pulses of nanosecond duration with a threshold power density of ~20 kW/cm2. It was shown that the appearance and parameters of the stimulated emission depend strongly on the concentration of ion-induced defects in Cu(In,Ga)Se2 thin films.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Cu(In</kwd><kwd>Ga)Se2</kwd><kwd>тонкая пленка</kwd><kwd>протон</kwd><kwd>дефект</kwd><kwd>стимулированное излучение</kwd><kwd>Cu(In</kwd><kwd>Ga)Se2</kwd><kwd>thin film</kwd><kwd>proton</kwd><kwd>defect</kwd><kwd>stimulated emission</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">M.
